 The T1SS I/O module expansion card provides a single socketed interface
channel for industrial standard miniature I/O modules to a 1-Wire bus. These
modules can accommodate AC voltages as high as 280 Volts and currents to 3 Amps.
DC voltages from 4 to 200 volts and currents to 3 amps. Dry contact relay output
modules such as the Grayhill 70M-ODC5R can also be accommodated. All these industrial
standard modules provide 4000 Vac isolation.
The T1SS has a built-in multidrop controller (DS2406), which provides a unique
64-bit registration number (8-bit family code + 48 bit serial number + 8 bit CRC)
assuring error-free selection and absolute identity; no two parts are alike. Unique
addressing allows I/O function to be identified absolutely, no more dip switch address
confusion. Status input, latched-input-activity and output-latch functions allow
input, output and fast event catch functionality to hundreds of I/O points on a
1-Wire bus.
The T1SS is designed to allow a network of isolated input and output modules
to operate on a two or three wire bus, power ("+"), common ("C") and signal ("S").
The T1SS can be powered locally or the power may be bussed with the1-Wire signal
in a three wire system. The bussed power can be unregulated 6V to 16V DC. The T1SS
provides onboard 5-volt regulation for I/O module operation. The onboard power supply
has a very low quiescent current and low dropout voltage to allow long cable runs
with minimum loss.
The T1SS can be stacked side by side for minimum panel space, or they can be
spaced hundreds of feet apart to minimize high voltage wiring. On board inline fuse,
LED status indicator and strain relief are provided for the I/O module.
The T1SS is compatible with the EDS OneSix DDE server and family of 1-Wire enabled
devices.
