Relay expansion module eP4

I/Omodularcompact-size

Overview
Expansion module for the sigmaPAC family of programmable controllers. Compatible with nP4 and AC3nP, it extends controller I/O capacity by providing additional analog, digital and relay channels.

Key features

• Universal analogue inputs configurable for voltage, current, thermocouples and RTDs
• Digital inputs: configurable 8/16 channels 24 Vdc plus 2 fast-counting inputs
• Analogue outputs: configurable 0/2/4 channels (voltage or current)
• Digital outputs: 8/16 channels 24 Vdc
• Relay/SSR drive: up to 4 relays for switching/SSR control
• Mounting: 6 DIN modules (105 x 110 mm)
• Power supply: 24 Vdc

Inputs
