Description Emulates behavior of Haltech IO 12 box. 4x 0v – 5v Analog inputs (built in switchable pullup resistors) 4x Digital Inputs DI1 – Reads Frequency, Duty and State (10hz-300hz) DI2-4 – Reads State Only (Switch to ground) 4x Digital pulsed outputs (low side switched) Change from IO Box A or B by soldering across the solder bridge marked “AB”. (by default IO is in A mode) Compatible with the following ECUs Haltech – PS, Elite and Nexus Link G4 , G4X, G5 MAXXECU ECU Master Pro, ADU and PMU Emtron (with custom firmware) – add a note to your order if you plan to use your device with an EMtron ECU Pullup resistors can be added for the Analog inputs by soldering across the relevant pads on the bottom of the board. Note: – 3A limit per channel, with a 7A overall limit for the outputs. – No frequency drive for the outputs. State or PWM only. (490hz or 980hz) – 0v-5v on the AVI. – Input protection for AVI, 12v tolerant. Still reads 0-5v – DPI1 can read frequency, duty and state. – DPI2, 3 & 4 are state only (on or off), No Frequency measurements. Pull to ground. Also 12V tolerant. – Built in pullup resistors are 1k ohm. Solder across the pads under rear cover to use them. – Swap from A mode to B mode by bridging the “AB” solder pads under the rear cover.
