  • I – Input Module
  • B – DC Voltage, Sinking Input
  • 8 – 8 Input Channels

Installation & Field Application Guide

  • Install in any available slot of the SLC 500 chassis. Ensure the power supply supports the 50 mA backplane draw.
  • Wire field devices to the 8 input terminals using appropriate gauge wire. Inputs are sinking type.
  • Verify field voltage is between 10-30 V DC. Nominal input current is 8 mA at 24 V DC.
  • For Class 1 Division 2 installations, follow hazardous area wiring practices and use approved barriers.

Why Choose the 1746-IB8

  • 8 sinking inputs provide reliable DC signal acquisition for SLC 500 systems.
  • Class 1 Division 2 approval for hazardous area installations.
  • Low backplane current (50 mA) minimizes power supply loading.
  • Proven reliability with UL, CE, and NEMA Noise Immunity certification.

Field Engineer FAQs

Q1: What is the difference between sinking and sourcing inputs on the 1746-IB8?

A1: The 1746-IB8 provides sinking inputs, meaning the input connects to the common (ground) to turn on. The input circuit sources current to the field device.

Q2: Can the 1746-IB8 be used with 24 V AC signals?

A2: No, this module is designed for DC input signals only. Use the 1746-IA8 for AC input applications.

Q3: What is the maximum cable length for field wiring to the 1746-IB8?

A3: Maximum recommended cable length is 305 meters (1000 feet) for reliable signal detection.
