Description: MTL 4526 Switch Operated Relay 2 CH IS Output New The MTL4526 enables two separate IS circuits in a hazardous area to be contact controlled by one or two, on/off, control signals in a safe area. Applications include the calibration of strain–gauge bridges; changing the polarity (and thereby the tone) of an IS sounder; the testing of IS fire alarms; and the transfer of safe-area signals into an annunciator with IS input terminals not segregated from each other. The output–relay contacts are certified as non–energy–storing apparatus, and can be connected to any IS circuit without further certification, provided that separate IS circuits are such that they would remain safe if connected together. Features: Number of channels Two, fully floating Location of control circuit Safe area Input/output characteristics Contact/Logic mode (Inputs suitable for switch contacts, an open–collector transistor or logic drive) Relay energised if < 450Ω or < 1V applied Relay de–energised if > 5kΩ or > 2V applied (35V max.) Loop powered mode Relay energised if >20V Relay de-energised if<17V Power supply failure protection Relays de–energised if supply fails Response time 25ms nominal Contacts (suitable for connection to IS circuits) 1–pole changeover per channel Contact rating 250V ac, limited to 40V dc for IS applications, 2A (reactive loads must be suppressed) Contact life expectancy 2 x 107 operations at maximum IS load Relay drive (see switch setting table) Choice of "loop-powered" or "contact/logic" control, for both channels, by switch selection. A further switch option ("1in2out") enables either input, in contact/logic mode, to activate both outputs. LED indicators Green: power indication Yellow: two: output status, on when relay energised Power requirement, Vs41mA at 20V dc44mA at 24V dc60mA at 35V dc Power dissipation within unit1.1W maximum at 24V Safety description (each channel) Non-energy–storing apparatus: relay contacts may be connected to any IS circuit without further consideration Payment: PayPal accepted. Contact should be made within 3 days and payment must be received within 10 days of winning. Payment must clear before shipping.
