Carlo Gavazzi SJ 105 230 Current Level Relay

Type: 1-phase AC/DC current metering relay (SJ 105 family)

Measuring ranges: 0.2 mA → 5 A, depending on model variant

Current input: Pin 5 & 7 for current measurement

Internal shunt: Yes (built-in)

Set-point: Adjustable with potentiometer (absolute scale)

Latching: Can be latched (by connecting pins 8 & 9)

Hysteresis: About ~10% (can be extended by external resistor)

Output: SPDT relay

Contact ratings:

• Resistive AC (AC1): 10 A / 250 VAC

• Inductive AC (AC15): 2.5 A / 230 VAC
