1.1.2 Features

· Low Power

+5Vdc @ 20mA (Max) regulated power and 5.8Vdc to 16Vdc @ 50mA (Max) unregulated power are supplied by the host/parent 3530-XXX via the 40-pin

Expansion Interface Connector P1.

· ESD & Transient Susceptibility

The RS-485 I/O circuitry has been designed to meet the requirements of IEC 801-2 for ESD withstand capability up to 10KV and the requirements of ANSI/IEEE

C37.90.1-1989 (formerly IEE 472) for surge withstand capability.

· EMI Compatibility

EXP485/AO Boards have been designed to coexist inside a shielded enclosure with the TeleFlow ä electronics. EMI radiation is insignificant and susceptibility is comparable or superior to associated electronics.

· Mounting

The EXP485/AO Board measures 3.75” (9.525cm) in width x 4.25” (10.795cm) in height and mounts piggy-back on a TeleFlow or TeleRTU CPU Board.

· RS-485 Comm. Port

EXP485/AO Boards provide an RS-485 communications port that is programmable for asynchronous rates up to 19.2Kbps. 3530-XXX units equipped with the

EXP485/AO Board can communicate with a network of 3530-XXX units (equipped
