The SRZ ( Z-TIO) is 4 channels digital temperature controller packed one compact module.
Z-TIO ( 4 channels type) module can have 4 CT ( current transformer) inputs. 3-phase heater can be monitored by allocating two CTs to one control channel.
Modules can be remotely distributed by connecting them via RS-485 communication. Up to 16 Z-TIO ( 128 DIs) and 16 Z-DIO ( 128 DOs) modules can be connected to one serial communication line by distributed installation.
The maximum number of modules connected by distributed installation is 31 modules.
