data sheet pxm this distributor is to be installed for each group of fc/ fcx series transmitter and receiving instruments, compact controllers and so on combined therewith. while receiving power from a system power supply, the distributor functions to provide dc power to a transmitter and convert current signal from the transmitter into voltage signal of 1 to 5v dc with a precision resistor for distribution to individual receiving instruments. 1. the terminal structure allows easy connection of an ex- ternal cable, and the transmitters of up to 4 loops are connectable to one distributor. 2. a current limiting circuit is provided for each loop, and an arrester can be built in at option. 3. an output backup function can be built in for prevention of short circuit faults. power supply voltage: 25.8v dc(supplied from power supply pxj) input signal: 4 to 20ma dc (input resistance 250 ? ) 4 to 20ma dc for reception (without transmitter power supply, 250 ? built in) capacity: 4 loops maximum transmitter power supply voltage: 24v dc output signal: 1 to 5v dc(output resistance 250 ? ) without output buffer amplifier function 1 to 5v dc(output resistance 250 ? ) with output buffer amplifier function - - 1 point per loop 1 to 5v dc(allowable load resistance 10k ? or more) - - 2 points per loop note: output buffer not provided for 0 + terminal with short circuit bar. accuracy: 0.1%. (versus full span with input sig- nal as reference) ambient temperature: 0 to 45 c ambient humidity: 90% rh or less mass{weight}: approx. 1kg intrinsically safe explosionproofing: usable as a distributor for zener barrier (pwzb1). external dimensions (h x w x d): 200 x 80 x 91.5 mm finish color: case; black (synthetic resin molding) cover; semi-transparent (synthetic resin molding) option: arrester can be built in at option. fc series distributor features specifications date EDS13-15G aug. 31, 1994
pxm notes: * (1) combined specification of with and without output buffer cannot be supplied. (2) specify the 9th digit so that it matches the 4th, 5th, 6th and 7th digits. (3) specify g or p in the 4th, 5th, 6th and 7th digits for combination with a zener barrier (pwzb1). (4) an arrester cannot be provided when the distributor is for zener barrier connection. code symbols x p m 2 2 1 345678 9 description 1st loop (*3) a b c d g h j k l p - application a b c d g h j k l p y a b c d g h j k l p y a b c d g h j k l p y 0 1 2 3 4 to 20ma for general application 4 to 20ma for reception only 4 to 20ma for general application 4 to 20ma for reception only for zener barrier connection 4 to 20ma for general application 4 to 20ma for reception only 4 to 20ma for general application 4 to 20ma for reception only for zener barrier connection 2nd loop (*3) 4 to 20ma for general application 4 to 20ma for reception only 4 to 20ma for general application 4 to 20ma for reception only for zener barrier connection 4 to 20ma for general application 4 to 20ma for reception only 4 to 20ma for general application 4 to 20ma for reception only for zener barrier connection none none none equipped equipped none none none equipped equipped none none none none none equipped equipped equipped equipped equipped 3rd loop (*3) 4 to 20ma for general application 4 to 20ma for reception only 4 to 20ma for general application 4 to 20ma for reception only for zener barrier connection 4 to 20ma for general application 4 to 20ma for reception only 4 to 20ma for general application 4 to 20ma for reception only for zener barrier connection none none none equipped equipped none none equipped equipped none none none none none equipped equipped equipped equipped equipped 4th loop (*3) 4 to 20ma for general application 4 to 20ma for reception only 4 to 20ma for general application 4 to 20ma for reception only for zener barrier connection 4 to 20ma for general application 4 to 20ma for reception only 4 to 20ma for general application 4 to 20ma for reception only for zener barrier connection none none none equipped equipped none none equipped equipped none none none none none equipped equipped equipped equipped equipped arrester circuit (*2) none (specify 0 when a, b, g is used in 4th, 5th, 6th, 7th digits) equipped (specify 1 when c, d is used in 4th, 5th, 6th, 7th digits) none (specify 2 when h, j, p is used in 4th, 5th, 6th, 7th digits) equipped (specify 3 when k. l is used in 4th, 5th, 6th, 7th digits) input signal none none none none none equipped equipped equipped equipped equipped (*1) output buffer none none equipped equipped (*4) none none equipped equipped arrester
