Z-4TC, 4-ch Thermocouple Input ModBus

Description:

The Seneca Z-4TC is a ModBus I/O device with 4 configurable thermocouple input channels. Each channel can be configured to a different thermocouple type with different filtering. The Z-4TC allows the user to select between higher sampling time or higher resolution, communications and sampling time are configured using the Z-NET or Z-PROG software.
