1.3.6.1 Non-isolated Analog I/O & Analog Input Modules (also see Section 2.3.4.5)
ControlWave EFM AI/O Modules provide 6 Analog Inputs and optionally 2 Analog
Outputs. All Analog Inputs are externally sourced, single-ended and individually Jumper
configurable for either 4-20mA or 1-5Vdc. Analog Outputs are externally sourced and are
individually Jumper configurable for 4-20 mA or 1-5 Vdc. 30Vdc Transorbs provide surge
suppression between each signal and ground. Analog Input Modules are identical to AI/O
Modules but have a depopulated AO section.
1.3.6.2 Non-isolated Digital Input/Output Module (also see Section 2.3.4.4)
ControlWave EFM DI/O Modules provide 12 Digital Inputs and 4 Digital Outputs. All
Digital Inputs support dry contact inputs internally sourced from the 3.3 Vdc supply and a
jumper selectable input current range of 60 uA (for low power applications) or 2 mA (for in-
plant noise immunity). 15 millisecond input filtering protects against contact bounce.
Digital Outputs have a 30 Vdc operating range and are driven by Open Drain FETs that
provide 100 mA (max) at 30Vdc. DI/O Modules support optional Status Indication with an
LED per I/O point. 31Vdc Transorbs provide surge suppression between each signal and
ground.
1.3.6.3 Non-isolated High Speed Counter Input Module (also see Section 2.3.4.6)
High Speed Counter Input (HSCI) Modules provide a total of 4 internally sourced inputs
that provide 2mA or 200uA (low power) input signals. Signal conditioning is provided by a
debounce circuit for a relay contact input source, followed by a one-shot pulse circuit that
generates a 65usec ±10% pulse. The signal conditioning circuitry also provides 20 micro-
second filtering. All Input circuits have surge suppression. HSC inputs can be individually
configured for dry contact or externally generated signal inputs. HSCI Modules are
provided with thirteen (13) user Configuration Jumpers that accommodate LED
enable/disable functionality, individual HSC input debounce enable/disable and individual
HSC 200uA or 2mA source for field connections.
1.3.6.4 Non-isolated Mixed Input/Output Module (also see Section 2.3.4.7)
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. All I/O circuitry is similar to those utilized on the I/O Modules discussed in sections
1.3.6.1 through 1.3.6.3.
1.3.7 ControlWave EFM Expansion Communications Modules
Expansion Comm. Modules provide two additional serial communications ports and op-
tionally the choice of a piggy-backed dial-line modem or piggy-backed 900 MHz Spread
Spectrum radio (or both). Both serial communication ports support speeds of up to 115.2
KB. The top Comm. port (labeled C1) supports RS-232 operation while the second one
(labeled C2) supports RS-485 operation. The RS-485 Port can optionally be ordered with
isolation to 500Vdc. Up to two Exp. Comm. modules may be installed (backplane slots 3 and
4).
