Ouman C203 is a DIN-rail mounted heating controller. Its versatility, intelligence and openness make it an ideal heating controller for all water circulation heating systems. Ouman C203 is really easy to use – informative display panel and GSM Control – feature enable reliable use anytime, anywhere! C203 can be connected to Ounet-service via M-LINK-adapter (TCP/IP, optional) or other monitoring systems using a Modbus RTU.

    • Analog outputs
    (27, 30, 43, 46, 49, 50): Output voltage range 0…10 V. Output current max 10 mA /output
    24 VAC voltage outputs
    (28, 41, 44, 47): Output current max 1 A /output. Without external power supply outputs current max. a total of 10 VA continuously, temporary (60 s) 15 VA.
    Relay outputs
    – Change-over contact relay (71…76): 2 pcs, 230 V, 1 A
    Triac outputs
    – 230 Vac (77…80): 2 pcs, 230 V, max 1 A / output. Potential-free AC switch. DC controls require intermediate relay.

    Data transfer connections
    – RS-485 bus (A1 and B1): Galvanically isolated, supported protocols Modbus-RTU
    Option
    – M-LINK: M-LINK adapter provides Modbus TCP / IP interface for C203 device.
    – GSMMOD: By connecting the modem to the C203 controller, you can communicate with the regulator text messages and pass this information on alarms to your mobile via SMS. The modem is connected to either the device or the M-LINK adapter RJ-45 connector. GSMMOD is powered by the C203 (terminal 52 and 53).
