Performance and Environmental Capabilities

• The module handles 16 individually isolated channels, which prevents cross-channel interference.
• It accepts a wide on-state voltage range from 10 VDC to 30 VDC for flexible field wiring.
• The short/inrush current reaches 250 mA peak and decays quickly to below 37% in 22 ms.
• Off-state voltage stays at 5 VDC maximum, so false triggering remains very low.
• Minimum on-state current is only 2.0 mA at 10 VDC, which supports low-power sensors.
• Maximum off-state current is 1.5 mA, keeping leakage under control.
• Input impedance reaches 31 KΩ maximum at 60 Hz for stable AC rejection.
• Programmable delay times let you tune response speed for different machine cycles.
• Power dissipation stays at 5.0 W maximum, which helps with thermal planning.
• Isolation voltage is 100% tested at 2546 VDC for 1 second on both channel-to-channel and user-to-system paths.

Installation Guide

• Mount the TC-IDJ161 on a compatible Honeywell backplane or chassis.
• Use the TC-TBCH 36-position terminal block for field wiring connections.
• Verify that the backplane current stays within the module power consumption data on page 46.
• Wire each input channel according to the 24 VDC nominal voltage and IEC Type 1+ compatibility.
• Check the on-state voltage range of 10–30 VDC before powering up the field devices.
• Set the programmable input delay time to match your control loop requirements.
• Confirm isolation voltage integrity after installation with a 2546 VDC test if needed.
• Keep the off-state voltage below 5 VDC to avoid unintended channel activation.
