The SSRMAN-1LP 4-20 mA Solid State Relay driver provides 0-100% PWM of any standard SSR. The PWM cycle time of the time proportioning is 350mS at the center but gets longer toward the end of the range to optimize the resolution of the output of the 4-20 solid state relay system. The calibration of the time proportioning converter can be adjusted by ordering option -ZS (zero and span pots). The SSRMAN-1LP can drive up to 4.2V @ 14mA offering a high performance, low cost solution to 4-20mA SSR systems.
