8. Local Adaptor for ON/OFF
Controller (SHA-KL4UG(B))
Connection as a Relay Control Unit
The local adapter output terminal and input terminal specifications are given
below.
Use the signals most appropriate for the type of equipment being controlled.
(1) Output terminals
The local adapter provides four styles of ON (set relay) and OFF (reset relay)
output signals for use by the equipment being controlled. Select the style
appropriate for your application. For more information, see the "Relay Circuit
Examples" section.

Input style Usage
Caution:
Note that the ON (set) relay output and OFF (reset) relay output have different
contact capacities.
(2) Input terminals
Status monitor signals from the equipment being controlled are received
by the relay contacts.
The local start/stop input uses a pulse style, so connect it to a
momentary input device, such as a push switch.
Individual permission:
Local prohibit:
OFF (continuous contact)
ON (continuous contact)
Caution:
When local prohibit (central) is set by the central control unit, the local
start/stop input will be ignored.
When stopped, the alarm input will be ignored.
