Milliamp Output Modules  

MAI mA Input Interface Module
Accepts a 0-20 mA input signal at 1.5 volts and produces a 0-20 mA at 20 volt signal to drive multiple loads/controllers. MAI can also accept a potentiometer input (135 Ohm thermostat or any 1K pot) and produce 4-20 mA @ 20 V to drive all SCR power controls, valve positioners, etc. The MAI can be modified to accept DC voltage inputs and convert them to a 4-20 mA control signal to drive SCR and TRIAC controls. (D.C. voltage input ranges must be ordered as options, contact us for availability). Operates on 120 VAC, 208-277 VAC, or 480 VAC.

MAP Series Manual Potentiometer 0-20 mA Output Source
Same as MAI but has potentiometer with 2 ft. of wire, 0-100 dial and knob ready for panel mounting. Works to control all "A" series controllers for open loop control. Operates on 120 VAC, 208-277 VAC, or 480 VAC. Will also work with 4-20 mA signal as an amplifier/trim adjustment.

MTP Series Manual Potentiometer Solid State Relay Driver
MTP produces a fast time proportioning 20 VDC signal for driving Solid State Relays (SSRs). MTP has a power output limit adjustment of 63 - 100%. The MTP accepts the same inputs as the MAI (potentiometer, mA, D.C. Voltage, or 135 Ohm thermostat). The MTP is supplied with potentiometer with 2 ft. of wire, 0-100 dial and knob. Can run over 10 SSRs.

For 4-20 mA Input SSR Driver use MITP.  MITP mounts onto SSR.

Dimensions:
All MAI, MAP, & MTP models
H x W x D in inches
3 x 4 x 1.75
Mounting: (2) 3.5 in. #6 or #8 screw

All MAI, MAP, & MTP are mounted to a standard snap-track.

All MAP, & MTP come with 500 ohm potentiometer. Set point pot needs 3/8 inch hole for panel mounting. MAI, MAP, & MTP can use 100 to 1000 ohm potentiometer.

0 - 100 scale 2.00 by 2.00 inches square. Knob is 1.1 inches in diameter.

All MAI, MAP, & MTP modules are isolated to 2500 V.
0 - 20 mA output is voltage regulated for maximum stability.
