B-3 Encoder, pulse and message inputs
2 signal inputs with common ground for reed contacts or transistor switches . No
extraneous voltages or currents should be fed in.
Designation
I1... I2
Cable connection
Screw terminals; 0.5 ... 1.5 mm² (solid);
With flexible cable use wire-end sleeves.
Special features
each input can be parameterised and sealed separately,
Input I2 can only be used as a signalling input
Max. cable length
max. 30 m depending on ambient conditions (EMC)
Nominal data
a) Use of input I1 as LF pulse or signalling input
and / or input I2 as signalling input
