Connectable load • Loads switched via 2 floating change-over contacts (DPDT)
• I~ max. 6 A (EEx de 4 A), U~ max. 253 V; P~ max. 1500 VA, cos ϕ = 1, P~ max. 750 VA, cos ϕ > 0.7
• I- max. 6 A (EEx de 4 A) to 30 V, I- max. 0.2 A to 125 V
• The following applies when connecting a functional low-voltage circuit with double isolation as per
IEC 1010: Sum of voltages of relay output and power supply max. 300 V
Power supply:
Please note the different voltage ranges
for AC and DC.
Output:
When connecting an instrument with
high inductance, provide a spark arrester
to protect the relay contact.
A fine-wire fuse (depending on the
load connected) protects the relay
contact on short-circuiting.
Both relay contacts switch simultaneously.
* When jumpered, the relay
output works with NPN logic.
** See below "Connectable load"

Note!
Please note the different voltage ranges
for AC and DC.
