PCI-1241/42 provides 5 dedicated output channels, and Figure 3-10
shows wiring diagram of local output channels. There are two types of
local output channels:
• 4-channel Servo On Outputs – A0_SERVON, A1_SERVON,
A2_SERVON, and A3_SERVON.
• 1-channel Position Ready Output – P_RDY.
Local Output Specifications
• Output voltage: Open collector 5 ~ 40 VDC
• Sink current: 100mA max. / channel; 500mA max. total
• 2500VDC isolation protection
Output Type
PCI-1241/42 output channels are all open collectors. When the output
signal value is “0”, an open collector channel is in “ON” state and the
load is activated. When the output signal value is “1”, an open collector
channel is in “OFF” state.
