Analog Setpoint Outputs

DESCRIPTION

All TWS Series institutional grade temperature transmitters are eld-programmable and are designed to satisfy the demanding requirements of pharmaceutical labs, hospitals, science labs, and other exacting applications. Internal jumpers control access to a feature which allows eld adjustment of calibration osets. Tampering can be prevented by setting a jumper to disable keypad program functions.

Analog Output

Analog output models feature a keypad to make adjusting temperature setpoint values easy. They are unique in reporting the setpoint values back to a control system by means of 4-20mA or 0-5/0-10VDC (output selected by slide-switch) signals.

Setpoint Relay

The TWS Series setpoint relay models measure temperature and oer thermostat functionality. Two separate relays can be congured to control heat/cool in thermostat mode.
