arranged in a single row); light when a signal is ON.
3 Cover for relay replacement Open to replace a relay. (KV-R16R/R8R only)
4 I/O terminal block Includes terminals for communication cables and
power supply input.
➮ Refer to connection diagram on page 1-186.
5 ADDRESS setting switch For setting addresses of I/O terminal modules
0–4 ch: Input module addresses
5–9 ch: Output module addresses
6 Input time constant selection For selecting input time constant (KV-R16X/R8X
switch only). Choose between the following:
0 ms
1 ms 10 ms
25 µs ±20% 1 ms ±20% 10 ms ±20%
7 Error hold switch Holds output when an error occurs.
(KV-R16R/R16T/R8R/R8T only)
CLEAR: Turns all outputs OFF when an error
occurs.
HOLD: Holds output when an error occurs.
Note: Use ADDRESS setting switches 0 to 4 for I/O terminal input modules and
