General Description
Features
Module type Digital Temperature Controller SRV
The SRV is a DIN rail mounted module type temperature controller. Dual loop control can be performed with a single compact module. A
maximum of 31 modules can be connected for 62-loop control. Power supply and communication lines are via a connector on the side, no wiring
required. Distributed installation via RS-485 is possible, enabling multi-zone distributed control system in a compact size.
Multi-zone space-saving and less wiring
Safe, and easy to use
Heat/Cool action
Heater/Loop break alarms
DIN rail mounting
Dual loop control can be performed with a single compact
module.
Separated installation by control zones is possible. Wiring to
sensors and output devices is minimized.
Modules can be installed separately inside a control panel or a
machine to reduce the physical size of the housing.
Space-Saving and Less Wiring
Safe, and Easy to Use
