Discrete-input transmitters

Honeywell has added two discrete-input transmitters to its family of XYR 6000 wireless devices. The STXW 500 and the STTW 401 transmitters can convert any measurement device with a contact-closure switch input into a wireless input, enabling manufacturers to decrease costs and improve efficiency by wirelessly monitoring more processes at their plants. The transmitters are suitable for applications such as wirelessly monitoring level switches, pump status and system alarms.

The devices can transmit signals from up to three contact switches. The STXW 500 transmitter accepts three discrete/digital inputs while the STTW 401 transmitter accepts a thermocouple input and two discrete/digital inputs. Additionally, both transmitters carry intrinsically safe approvals for use in hazardous areas from FM Global and the Canadian Standards Association.

The transmitters complement the other wireless transmitters in Honeywell’s XYR 6000 product line, which includes: absolute and differential pressure transmitters, temperature transmitters, analog transmitters, corrosion monitoring transmitters and gauge pressure transmitters.
