SR360
Alarm Unit
with Current and
Voltage Input and
Double Relay Outputs
Input connections
Voltage
Current
SR360 is designed for monitoring current and voltage signals in the process
industry.
Two output relays with individually adjustable trip functions are available.
LED’s in the front indicate alarm state and correct power supply.
Output connections
Relay 1
• Current and voltage input
• Two relay outputs with independent switch functions
• Monostable relays for safe tripping at power failure
• SPDT relays with 6 A switch capacity
• High configuration flexibility with DIP switches
• Trip levels and hysteresis adjustable from the front
• Three front LED’s for trip indication and power supply monitoring
• 4 kV isolation between input, output and power supply
• Protective Separation acc. to EN 50178
• Universal 24 V AC and DC power supply
• DIN-rail mounting
