505-6108A SIEMENS Analog IO Modules
The Input Modules (PPX:505–6108A ) offer the additional benefit of an optional ±10 V input range, and they do not require external user-supplied power. The Output Modules (PPX:505–6208A, and PPX:505–6208B), like the double-wide PPX:505–6208, require user-supplied 24 VDC power to maintain low power consumption from the base.Analog I/O Modules.
