Selection Suggestions and Precautions
Selection Suggestions:
- Confirm that 24–28 V power supply matches your control panel voltage.
- Ideal when you need one control output (switched DC), two relay outputs (alarms or secondary functions), and RS-232 communication.
- Suitable for applications requiring remote monitoring or integration with a PC/PLC via serial link.
- Verify sensor type compatibility (thermocouple, RTD, or process signal) before installation.
Precautions:
- This model has no auxiliary Input 2 (no event input or remote setpoint input).
- Use appropriate fusing and wiring practices according to local electrical codes.
- Ensure proper grounding and shielding for thermocouple/RTD wiring to maintain accuracy.
- RS-232 communication requires correct cabling and software configuration (Modbus RTU typically supported).
- Do not exceed the relay contact ratings (2 A).
- This model is discontinued by the manufacturer; availability is limited to existing stock or refurbished units. Consider current Watlow Series equivalents for new designs.
