with EXP485/AO Boards), even though a radio or modem may be installed on the
CPU Board’s network port.
1.2 COMPONENT IDENTIFICATION
EXP485/AO Boards do not contain LEDs or switches. Fully populated EXP485/AO Boards
(P/N 392971-01-0) are provided with seven (7) configuration jumpers (see Figures 1 & 11).
Depopulated EXPAO Boards (P/N 392971-02-0) are factory set for 1-5Vdc AO operation and don’t have configuration jumpers (see Figure 2). Two connectors are provided; 40-pin connector P1 mates with the host 3530-XX-X (connector J4 - TeleFlow CPU or J18 - TeleRTU
CPU) and accommodates the TTL interface between the two entities, while 9-pin connector
TB1 mates with the RS-485 device that is being interfaced to the 3530-XXX and/or an analog output device. Additionally, the 3.5mm pitch plugable connector TB1 is removable from its mating EXP485/AO Board socket.
1.3 INSTALLATION COMPATIBILITY
An EXP485/AO Board can be installed into any of the following 3530-XXX models:
3530-10B - TeleFlow
3530-15B - TeleRTU
3530-35B - TeleRTU Module
3530-40B - TeleFlow ECR
3530-20B - TeleFlow Plus 3530-50B - TeleFlow Corrector
3530-25B - TeleRTU Plus
1.3.1 Restrictions
The 3530-XXX in question must be equipped with ACCOL application software. The
TeleFlow Plus (3530-20B), TeleRTU Plus (3530-25B) and the TeleRTU Module (3530-35B) support installation of either a Low Power I/O Expansion Board (LPI/OEB), an
EXPCOM232 Board, or the EXP485/AO Board discussed herein, i.e., YOU CAN ONLY
INSTALL ONE (1) OF THESE ITEMS .
EXP485/AO Board (P/N 392971-01-0) is fully populated and supports RS-485 network communications and interface to either a 1-5Vdc or a 4-20mA analog output device.
P/N 392971-02-0 is a depopulated version of the EXP485/AO Board and only supports interface to a 1-5Vdc analog output device. Connector TB1 has two usable pins (08 = AO and 09 = AOGND). This version is designed for use in a Class I, Division 2, Groups C and D nonincendive environment or a Class I, Division 1, Groups C and D intrinsically safe environment.
Intrinsically safe EXPAO Boards can be installed in 3530-XXX units with 6V Lead Acid or
7.2V Lithium battery systems.
