STANDALONE CARD- 2. ADDRESSED BY SWITCHES- 3. OPEN COLLECTOR OUTPUTS- RS232 CONTROL. Discontinued Specifications, Prices & Availability may change without notice. Images are for illustration purposes only. E&OE Features This relay card can be used in several ways : stand alone card, addressed by switches or open collector outputs or remote controlled through RS232.In option remote controlled using RF (radio frequency) signals (K8058 remote control + RX433N module). Since the card can be addressed using RS232 commands, you may write custom applications in any programming language on any platform.Test software can be downloaded from our web site.DIAGNOSTIC / TEST SOFTWARE:Separate relay on/off test with moment or toggle functionClear all / set all relays functionAddress selection: up to 255 cards can be selectedEmergency stop for all cardsMinimum system for test software: Pentium class CPUWindows 95 or higherMouse and free RS232 port8 high quality relay contacts: 5A/230Vac max.Relay outputs are transient suppressed using VDRsLED confirmation on each relay contact8 drive inputs to use with open collectors or regular switchesRS232 input to drive the card with computer or terminal: baud rate: 2400, no parity, 8 data bits, 1 stop bit, high or low impedance selection (10K or 1K)Optional RF driving possibility using RX433N type module (not simultaneous with RS232) together with K8058 eight channel RF remote controlPower output: unregulated 12Vdc / 200mAPower Supply: 12Vac / 500mA (including 12V output)Diagnostic software downloadable from our siteDimensions: 160 x 107 x 30mm (6.3" x 4.2" x 1.2") Additional Information Group Computer / Interface / Programmers Model K8056 PCB Size 160x107x30mm Voltage 12VAC Current 500mA
