Supply voltage

12-30 VDC

Signal input

Transmitter LWLS-T (switchboard) uad LWL-T (housing for outdoor applications)
Signal input (from encoder):
Incremental: 0°, 90°, N, STATUS; each with inverted signals
Signal transmission (outputs transmitter module):
Optical (to decoder): Fiber optic 62.5/125 μm or 50/125 μm with ST plug-in connector
Signal level:
HTL or TTL (RS 422A)

Signal output

Decoder LWLS-D and LWLS-Di (galvanically isolated output blocks)
Signal output (to controller):
Incremental: 0°, 90°, N, STATUS; each with inverted signals
2 output blocks, optional additional galvanic isolation between the two output blocks (type LWLS-Di)
Signal transmission (inputs decoder module):
