Module Features & Protection

Zero-crossing Triac switching minimizes electromagnetic interference (EMI) and extends load life.
Full isolation between each output and from controller logic enhances system safety and noise immunity.
Integrated MOV protects against voltage spikes and transients on the AC line.
Field-replaceable fuses (3.15A time-lag) protect each output from overload and short-circuit conditions.
Shorting comb accessory simplifies wiring when all outputs share a common AC voltage source.
Configurable failsafe operation ensures predictable behavior during communication loss or system fault.
Low leakage current minimizes energy waste and prevents unintended activation of sensitive loads.

Installation & Wiring Guidelines

Install in a compatible Honeywell HC900 rack. Ensure the AC line voltage is within 85-240V AC.
Use appropriate wire gauge for the load current (up to 2A per channel).
For inductive loads (solenoids, contactors), consider using an external snubber circuit to reduce EMI.
When using the shorting comb, connect the common AC source to the comb and then to the barrier terminal block.
Replace blown fuses only with the specified 3.15A time-lag type (e.g., Littelfuse 37413150410).
Observe the minimum load requirement of 50 mA; for smaller loads, a parallel load resistor may be necessary.
Ensure proper heat dissipation; do not exceed the total module current rating of 8A.
