HIMA Z7136 (Old H41q/H51q system 16-channel digital output DO module, SIL3)

Z7136 is a 16-channel digital output DO module (relay type) for relays, SIL3/AK6, from the old platform of HIMA H41q/H51q/HIQuad X (legacy system). It is used to drive switch loads such as solenoids, contactors, and alarm lights in ESD/SIS systems, along with Z7116 (DI), Z7126 (AI), and Z7127 (AO), which belong to the legacy system I/O and are not compatible with the HIMax X series.

1. Model Positioning (Quick Differentiation within the Same Series)

Z7116: 16-channel Digital Input DI (24VDC)

Z7126: 16-channel Analog Input AI (4-20mA)

Z7127: 16-channel Analog Output AO (4-20mA)

Z7136: 16-channel Digital Output DO (Relay, SIL3) ✅
