Multi-Loop Limit and Alarm Scanners
The Watlow multi-loop limits and alarms are a low-cost solution for multi-channel, redundant temperature monitoring. These limits and alarms can continuously monitor thermocouples, RTDs or thermal switches, making them ideal for multi-zone applications.
| Controller | DIN Size | Function | Accuracy | Operating Environment |
|---|---|---|---|---|
| TLM-8 Thermal Limit | Panel or DIN-Rail mountable | Limit | ±5% of limit at 25°C | 0 to 60°C (32 to 140°F) |
| CAS200 Alarm Scanner | 1/8 | Alarm | 0.07% at 25°C | 0 to 50°C (32 to 120°F) |
Applications
- Any process requiring multi-channel redundant temperature monitoring
- Semiconductor capital equipment
- Electronics packaging equipment
- Plastics injection molding and extrusion equipment
