{"product_id":"elsema-pck43304w-pentacode-transmitter-external-inputs","title":"Elsema PCK43304W 4-Channel 433MHz PentaCODE Transmitter with External Inputs","description":"\u003cp\u003eThe \u003cstrong\u003eElsema PCK43304W\u003c\/strong\u003e is a 4-channel 433MHz PentaCODE® transmitter with hardwired external inputs — a purpose-built bridge between fixed-wired control gear and Elsema's wireless PCR receiver range. Connect a push button, toggle switch, limit switch, relay contact or PLC dry-contact output to one of its four inputs, and the transmitter converts every activation into a secure wireless signal.\u003c\/p\u003e\n\u003cp\u003eIt's the right part for sites where running cable to a receiver is difficult, disruptive or expensive — retrofitting an existing control panel with wireless gate triggering, linking an alarm panel's relay output to a remote annunciator, taking a PLC output wirelessly to a motor starter on the other side of a yard, or adding wall-mounted wired buttons to a system that's otherwise driven by key fobs.\u003c\/p\u003e\n\u003cp\u003eSecurity is handled by Frequency Hopping Spread Spectrum (FHSS) across five 433MHz frequencies, with PentaCODE® dual coding for setup flexibility: classic 12-way DIP switch for quick pairing, or encrypted mode with over 17 billion combinations for high-security installations. Simultaneous transmission is supported, so closing two inputs at once sends both channels together — no missed triggers on multi-button panels.\u003c\/p\u003e\n\u003cp\u003eThe PCK43304W runs on 12V AC\/DC with a very low 6µA standby current (27 mA when transmitting), which makes battery-powered installations entirely practical. In off-delay mode, a held input triggers short repeating bursts rather than a continuous carrier — keeping the RF channel clear for other devices to operate in the same area. Typical range is up to 500 metres line-of-sight.\u003c\/p\u003e\n\u003cp\u003eCompatible with the full Elsema PCR433 series of receivers (1, 2, 4 and 8 channel; 12–24V AC\/DC and 110–240V AC supply options).
