- Output signal specifications
DC output signals B are used to drive indicator LEDs and relays on
the machine. Transistors are used for the driver.
(1) Output transistor ratings
(a) Maximum load current at output ON
200 mA max. including momentary current
(b) Saturation voltage at output ON
1.6 V max., 1.0 V typ. at load current of 200 mA
(c) Withstand voltage at output OFF
24 V ±20% max. including momentary voltage
(d) Leakage current at output OFF
100 µA max.

NOTE
Connect 0V on the machine power supply to 0V on
the control unit (CM41-A10, B10, CM42-A10, B10).
Do not make a ground connection on the machine
side.
(3) When an inductive load such as a machine-side relay is
connected, be sure to attach a spark killer. Ensure that a spark
killer is inserted as close as possible (within 20 cm) to the load.
When a capacitive load is connected to the machine side,
current-limiting resistors must be inserted in series, and the
machine must be used within the rated current and voltage
including momentary current and voltage.
(4) When lamps are lit directly by transistor output, rush current
may flow and damage the transistor. For this reason, provide a
protection circuit as shown above, and use the machine within
the rated current and voltage including momentary current and
voltage.
