Electronic Relay Incorporated Solenoid Operated Directional Valves
The valve is actuated by operating a built-in switch using a very small current signal(about 10 mA) when the solenoid is energised.
● A Direct drive by the programmable controller is now possible
As the valve can be actuated by a very small current signal (about 10 mA), a Direct Drive ispossible on the output circuit of the programmable controller or sequence controller.
● Simple construction and stable operation
Since the valve is a direct type, the construction is quite simple. Also the solenoid is thewell proven wet armature type, which can withstand contamination. Therefore a stable
operation can be obtained.

■ Comparison of The Conventional Type and The Electronic Relay Incorporated Type

Programmable
Controller● Output Unit・Large capacity output units (approximately 2A perunit) are required to operate solenoid operated
directional valves.
・As there is a limitation for common capacity, allcontacts of the output units can be used in some cases.
・Total cost therefore becomes higher, and a larger
installation space is required.

● Power Supply Cables

・As each double solenoid valve requires a minimum of
three cables, it is obvious that the more valves youuse, the more power supply cables and wiring isnecessitated.
This may increase the possibility of miswiring.
・Miswiring and short circuits may damage a very
expensive programmable controller and output units.

Control Board

Thick wires are required
and therefore, wiring isawkward.

Conventional TypeElectronic Relay Incorporated Type● Output Unit
ProgrammableController
Control Board

・Standard small capacity output unit, which is usually lessexpensive can be used.
・Other electric devices can be commonly used with thesolenoid directional valves. Therefore, installation oroutput units can be reduced.

● Signal Output Cables

・Thinner cable, compared with power supply cable, canbe used and therefore wiring is easier.
・The solenoid operated directional valve is provided
with a protective circuit to ensure a constant current,
which protects the programmable controller fromserious effects caused by miswiring.

Common Cables

Solenoid Power Supply

・Only two power supply cables arerequired for solenoid operated
directional valves and use only
common cables for adding valves,
therefore can reduce wiring man-hour.

Item————● Please wire correctly to the receptacle. Power terminals are fixed (+) and (-) sides. Please use smoothing power source for DC power supply.
● There is no time lag between signal output cables switch (ON/OFF) and solenoid switching (ON/OFF).
● Signal output cables do not need to use shield cables.
● This valves of external signal type, the signal terminal and power terminal are insulated. So that surge voltage which generated when solenoid off
will not affect to control units connecting signal output cables. (Internal signal type generate surge voltage, so please install surge killer as
required.)Electronic Relay Incorporated Solenoid Operated Directional Valves
