M-system R1M Series, R1M-GH Reference Manual
M-System R1M-GH is a remote I/O device with 16 thermocouple or DC inputs. It allows for easy system expansion via Modbus RTU communication protocol. The device supports both RS-232-C and RS-485 communication interfaces. With a transmission distance of up to 10 meters for RS-232-C and 500 meters for RS-485, it provides flexible connectivity options. Additionally, the M-System R1M-GH features a RUN indicator LED that blinks green in normal conditions, providing visual feedback on the device's status.

When the device is not at the end, remove the jumper pin.
Remark 1: This device is not designed to cancel noise included in the input signals.
Be careful to eliminate such noise by using shielded cables.
Remark 2: Be sure to maintain the same potential at all the common negative terminals for DC input.

BEFORE USE ....
Thank you for choosing M-System. Before use, please check contents of the package you received as outlined below.
If you have any problems or questions with the product, please contact M-System’s Sales Office or representatives.
This product is for use in general industrial environments, therefore may not be suitable for applications which require higher level of safety (e.g. safety or accident prevention systems) or of reliability (e.g. vehicle control or combustion control systems).
For safety, installation and maintenance of this product must be conducted by qualified personnel.
■ PACKAGE INCLUDES:
Remote I/O module (body + CJC sensor) ..................... (1)
■ MODEL NO.
Confirm Model No. marking on the product to be exactly what you ordered.
■ INSTRUCTION MANUAL
This manual describes necessary points of caution when you use this product, including installation, connection and basic maintenance procedures.
For detailed information on Modbus supported functions, refer to Modbus Protocol Reference Guide (EM-5650).
The R1M is programmable using the PC configurator software. For detailed information on the PC configuration, refer to the R1CON instruction manual. The R1CON PC
Configurator Software is downloadable at M-System’s web site: http://www.m-system.co.jp.
MODEL
R1M-GH
■ POWER INPUT RATING & OPERATIONAL RANGE
• Locate the power input rating marked on the product and confirm its operational range as indicated below:
100 – 240V AC rating: 85 – 264V, 47 – 66 Hz, approx. 10VA
24V DC rating: 24V ±10%, approx. 7W
■ GENERAL PRECAUTIONS
• Before you remove the module, turn off the power supply and input signal for safety.
■ ENVIRONMENT
• Indoor use
• When heavy dust or metal particles are present in the air, install the module inside proper housing with sufficient ventilation.
• Do not install the module where it is subjected to continuous vibration. Do not apply physical impact to the module.
• Environmental temperature must be within -5 to +60°C
(23 to 140°F) with relative humidity within 30 to 90% RH in order to ensure adequate life span and operation.
• Be sure that the ventilation slits are not covered with cables, etc.
■ WIRING
• Wrong connection may damage the module.
• Do not connect cables to moving parts or pull them tightly.
• Do not install cables (power supply, input and output) close to noise sources (relay drive cable, high frequency line, etc.).
• Do not bind these cables together with those in which noises are present. Do not install them in the same duct.
■ AND ....
• The module is designed to function as soon as power is supplied, however, a warm up for 10 minutes is required for satisfying complete performance described in the data sheet.
POINTS OF CAUTION
■ CONFORMITY WITH EC DIRECTIVES
• This equipment is suitable for use in a Pollution Degree
2 environment and in Installation Category II, with the maximum operating voltage 300V.
Basic insulation is maintained between the signal input and RS-232C/RS-485. Prior to installation, check that the insulation class of this unit satisfies the system requirements.
• Altitude up to 2000 meters
• The equipment must be mounted inside a panel.
• Insert noise filters. Okaya Electric Industries Model SUP-
E1H or equivalent for the power source connected to the unit, and TDK Model ZCAT3035-1330 or equivalent for the RS-232C cable are recommended.
• The equipment must be installed such that appropriate clearance and creepage distances are maintained to conform to CE requirements.
• The actual installation environments such as panel configurations, connected devices, connected wires, may affect the protection level of this unit when it is integrated in a panel system. The user may have to review the CE requirements in regard to the whole system and employ additional protective measures to ensure the CE conformity.

■ RS-232C INTERFACE
*
When the device is located at the end of a transmission line via twisted-pair cable,
(when there is no cross-wiring), close across the terminal T2 – T3 with the attached jumper pin (or with a leadwire).
When the device is not at the end, remove the jumper pin.
Remark 1: This device is not designed to cancel noise included in the input signals.
Be careful to eliminate such noise by using shielded cables.
Remark 2: Be sure to maintain the same potential at all the common negative terminals for DC input.

CHECKING
1) Terminal wiring: Check that all cables are correctly connected according to the connection diagram.
2) Power input: Check supply voltage.
3) Input: Check that the input is within 0 – 100% of fullscale.
4) DIP SW setting: Check that all switches are set correctly.
ADJUSTMENT PROCEDURE
This unit is calibrated at the factory to meet the ordered specifications, therefore you usually do not need any calibration.
MAINTENANCE
Regular calibration procedure is explained below:
■ CALIBRATION
Warm up the unit for at least 10 minutes. Apply 0%, 25%,
50%, 75% and 100% input signal. Check that the output signal for the respective input signal remains within accuracy described in the data sheet. When the output is out of tolerance, please contact M-System’s Sales Office or representatives.
