The Watlow TLM (thermal limit monitor) series is a compact, cost-effective thermal limit monitor solution for multi-channel, redundant temperature monitoring. Each TLM has eight channels to continuously monitor thermocouples, RTDs, or thermal switches, making it ideal for multi-zone applications. Choose an individual temperature limit for each channel from the standard list or consult the factory for other limits.
The thermal limit monitor is equipped with flexible interlocks, which are designed to interface with redundant controls. The alarms latch and require operator intervention to clear for process and equipment protection. Semiconductor capital equipment OEMs will find these features ideal for meeting SEMI S2 safety guidelines.
The TLM is compact and easy to install on a panel or a DIN-rail. No cutout is required, reducing installation and fabrication costs. Troubleshooting is simplified through a self-test diagnostics input, which simulates the alarm state. The TLM-8 is FM approved as a temperature limit switch, bears the CE mark (LVD and EMC Directives) and is UL® and C-UL® listed.
