- 10. Detail Description MOSFET Output PowerMate 15 has 16 MOSFET Outputs which are rated at 25 Ampere each maximum. All switches can only Switched to Battery. Each Output is double protected by hardware and software, PowerMate 15 can shut down the MOSFET in case of over-current, and in case of software exception the fuse will be blown to protect the circuit from further damages. Default Software Setting will switch OFF the MOSFET within 300ms in case of an over-current event. This is programmable to change from 100ms to 3s. For other trip-over values, please consult our sales. Binary Input PowerMate 15 has 16 Binary Inputs which are capable of reading Digital High / Low Input. Each Binary Input can be configured as STG Active / STB Active independently: 1. STG Active regards GND as logic “1” input and regards VDD (7-30V) as “0” input. 2. STB Active regards GND as logic “0” input and regards VDD (7-30V) as “1” input. · ALL Binary Input default configured as STB Active inputs. Binary Input Model: When the Pull-Up is set to pull to GND, it can prevent false trigger in case there is water leakage which short the input to the GND. That also prevents the input to be used as one wire low water probe which short to chassis ground through water. Instead, floating micro-switch or 2 wire resistive sensors should be used instead.
