The compact and cost effective 7SL Limitrol provides a process safety limit in a 1/16 DIN package. The 7SL is designed specifically for equipment manufacturers who require an FM approved high limit safety. NEMA 4X faceplates allow these units to be used in severe environments. The red 4-digit, 7- segment numeric and 2-digit alphanumeric displays allow the operator to configure the 7SL with easy to use codes. The 7SL has an FM approved Form C relay output that can be configured for a high (heating process), low (cooling process) or high/low limit (special process). In the high/low mode, the process must be within the two independent setpoints or the relay resets. |
The FM alarm can be configured for automatic or manual restart on power-up. The 7SL has an optional additional alarm that can be configured as a process high, low, band or deviation alarm with direct or reverse action. This alarm acts as a process event to begin data acquisition or recording as the process nears an unsafe condition. It can also be configured for automatic or manual reset and for a standby sequence to mask alarms on start-up. Options include a digital input for alarm acknowledgement, serial Modbus® or JBUS communications and a 24 Vac/Vdc power supply. The unit can be either panel mounted, or wall or DIN rail mounted using the DIN Rail mounting accessory. |
