MPA 41: 4-Channel Multiplexed Photoelectric Amplifier.pdf

0-35 m, Diffuse proximity: 0-2 m. Supply voltage: 230 V ac, 115 V ac, 24 V ac or 24 V dc. Manual sensitivity adjustment, adjustable on/off time delay, 4 relays and/or 4 transistor individual outputs, 1 relay and 1 transistor common output. Switch selectable light or dark function, switch selectable long or short range. Power, output and signal level indicators, screw terminals connection.

The MPA 41 is a 4-channel, multiplexed photoelectric amplifier used with remote transmitters LT and receivers LR. Each channel operates independently with its own transmitter and receiver, preventing optical cross talk. The amplifier offers a choice between individual relays and/or transistor outputs, or a common relay and transistor output with adjustable on/off time delay. Manual sensitivity adjustment is available for each channel via integral potentiometers.

Technical data for MPA 41 A, B, C, and D includes supply voltage, voltage tolerance, current consumption, output, alarm output, power on indicator, output indicator, signal level indicator, and hysteresis. Relay and transistor operation frequencies and response times are also specified. Housing material is polycarbonate, and environmental data includes temperature operation and storage, and sealing class IP 30.

Applicable remote sensors and ranges for MPA 41 A/B and C/D include thru-beam and diffuse proximity sensors with short and long range options. Wiring diagrams are available for different types of MPA 41, including 4 individual NPN/PNP outputs, 4 individual relays, and 1 common relay and 1 common transistor output.

Dimensions and descriptions for MPA 41 A/C and B/D include power on indicator, output indicator, sensitivity adjustment, and signal status indicator. Common on delay and common off delay are also specified.
