Wireless crane remote control | 2 transmitters + receiver | 2 buttons + START/STOP | 1 speed | 315 MHz | 100–240 V AC | ES-E1738-315B

Radio control set with 2 transmitters and a 315 MHz modular receiver

ES-E1738-315B is two transmitters and one modular receiver for a simple single-axis mechanism, such as a hoist or a gate. Each transmitter has ▲, ▼, START and STOP buttons. The command goes by radio to the receiver, whose relay closes the channel and energises a contactor coil – the motor is switched by the contactor.

• 2 transmitters for one receiver – control from two places or a spare remote
• ▲ and ▼ buttons – one axis: hoist, gate, damper
• Separate START and STOP – the system stays inactive until the operator enables it
• 100–240 V AC supply – connects directly to a 230 V AC control circuit
• Compact 95×62×29 mm module – fits a small enclosure

• AK-C211008 – 433 MHz, 1 transmitter with 4 direction buttons, channel load up to 10 A
• ES-ML-K2 – 868 MHz, 1 transmitter, receiver in an IP66 housing, 230 V AC
• F21-2S-b3ce – also 2 transmitters, but receiver in an IP66 housing, 6 channels, up to 100 m

• Material and goods hoists operated from the bottom and the top
• Gates and barriers operated from two posts
• Small electric winches
• Dampers and lifting platforms
• Auxiliary mechanisms that need a spare remote

• The receiver relays switch contactor coils only (up to 4 A) – never pass motor current through them.
• Mount the receiver in an IP enclosure or panel; the open board must not be exposed to moisture or dust.
• Wire the STOP channel into the main contactor KM0 circuit; loss of the link must stop the mechanism (EN 60204-32) – test with both transmitters.
• Organise work so that only one operator controls the mechanism at a time.
• Limit switches (SQ) and NC interlocking of ▲/▼ stay in the circuit.
• Before installation or repair – LOTO on the main isolator.

Quick selection guide

Check before ordering:

• Does the contactor coil voltage match the 100–240 V AC receiver supply?
• 315 MHz: check whether the frequency is permitted in your country.
• Is one axis (▲/▼) at one speed enough?

ES-E1738-315B – one mechanism, two control posts

2 transmitters with ▲▼ + START/STOP and a 315 MHz modular receiver for simple single-axis mechanisms. Mount the receiver in an IP enclosure and check that 315 MHz is permitted in your country.
