SR336

Alarm Unit with RTD Input and Double Relay Outputs

SR336 is an alarm unit with programmable alarm functions designed for temperature monitoring with RTD sensors in 2-wire sensor connection in the process industry. Two output relays with synchronous switching are available with functions such as MIN/MAX alarm in open-circuit or closed-circuit operation. LEDs in the front indicates alarm state and correct power supply.

• Input from any RTD sensor or resistance signal in 2-wire sensor connection
• Selectable input ranges 0-300 ohm or 0- 3 000 ohm
• Two relay outputs with synchro­nous switching and functions
• Monostable relays for safe tripping at power failure
• SPDT relays with up to 6 A switch capacity
• The switching point and the switching hysteresis are set with potentiometers from the front
• Relay functions are set with DIP switches from the front
• Front LEDs for monitoring states and power supply monitoring
• High 4-port isolation
• Protective separation acc. to DIN EN 61140 by reinforced insulation acc. to DIN EN 61010
• 24 V DC power supply
• Mounted on a standard 35 mm DIN-rail
