Description

2500 Series®  PLC System

The 2531 32-Point Form-A Relay Output Module

provides 16 or 32 Form-A outputs isolated in

groups of eight for the CTI 2500 Series® or

Simatic® 505 I/O base. The module uses relay

output circuits to switch on or off external devices

such as pilot lamps, motor starters, or solenoids.

The 2531 is designed to switch externally

supplied 15 to 240 VAC and 15 to 30 VDC. The

internal logic signals are isolated from the

external outputs to 2100 VDC.
