signals, or relay contacts. A serial EEPROM contains HSC Board serialization data. Each
input of the HSCI Module is configured as a 16-bit high-speed counter.

2.3.4.7 Non-isolated Mixed I/O Module (see Figures 2-22 & 2-23)
Non-isolated Mixed I/O Modules provide a total of 6 individually field configurable Digital
Inputs/Outputs, 4 Analog Inputs, 2 High Speed Counter Inputs and 1 optional Analog
Output. I/O circuitry is similar to those utilized on the I/O Modules discussed in sections
2.3.4.4 through 2.3.4.6.
Surge Suppression and signal conditioning is provided for each DI. DO circuits consist of an
open drain MOSFETs and Surge Suppression. Mixed I/O Modules provide internally
sourced DI operation for Dry Contacts pulled internally to 3.3Vdc when the field input is
open. Each DI is protected with a surge suppressor. DI filtering is 15 milliseconds. DOs are
composed of open drain MOSFETs and surge suppressors.
Mixed I/O Module AIs are independently configurable for 4-20mA or 1-5 Vdc single ended
operation. Each AI signal is channeled through signal conditioning circuitry (that provides
a 2 Hertz low pass filter), a transorb for surge suppression, multiplexer, and an A-to-D
Converter (ADC).
Non-isolated Mixed I/O Modules support a total of 2 HSC inputs provided with surge
suppression, bandwidth limiting and 20 microsecond (50kHz) filtering. HSC inputs may be
individually field configured with contact debounce circuitry enabled or disabled and for
2mA or 200uA (low power) operation. HSCs are supported by signal conditioning circuitry
consisting of a debounce circuit followed by a one shot pulse circuit that generates a 65
microsecond
±10% pulse and limits the maximum frequency of an input signal to 15kHz.
Field inputs can be driven signals, or relay contacts. Each input of the HSCI Module is
configured as a 16-bit high-speed counter.
