1.2.2 Output module

(1) If an output module drives load, its maximum switching frequency must be on for
(2) If a counter or timer which has a DC-DC converter as a load is used with an output
(3) Fuses installed to an output module cannot be replaced.
(4) Fuses installed to an output module are to prevent external wiring from being

(b) The high-speed input modules switch module types (high-speed input or
interrupt input) for 16 input points all together and between valid and invalid
noise filters as shown below.

*1: When selecting an improper module type, an error (error code: 2100)
occurs.
*2: Setting the input response time with GX Developer is ignored.
(c) If the small number of value of input response time is set, the modules tend to
have impact of noise. Ensure that the modules do not have impact of noise.
For the details of the measure against noise, refer to QCPU User's manual
(Hardware Design, Maintenance and Inspection).
(d) The high-speed input modules connected with electric appliance such as
relays may load a chattering as a signal.
(e) Select a cable whose length is three meters or less, when using the high-
speed input module as a CE-compatible product.

module, choosing an output module by its average current can cause a failure due
to periodic inrush current at power-on or during operation.
To reduce the influence of inrush current for use of the above load, connect a
resistor or an inductance to the load in series or use a module whose maximum
load current is large.

Therefore, if the fuses became a failure due to other than a short-circuit, the output
modules may not be protected.
