TM 5-3895-374-24-1 RTB -Removable Terminal Block Signal Delay- For inputs, the response time required to transmit the circuit status from the field wiring to the digital logic For outputs, the time required to transmit the circuit status from digital logic to the output wining Sinking- A term used to describe current flow between an 1/0 device and SLC I/O circuit- typically, a sinking device or circuit provides a path to ground, low, or negative side of power supply Sinking/Sourcing-  Describes  a  current  signal  flow  relationship  between  field  input  and output devices In a control system and their power supply.  Sourcing I/O modules supply (or source) current to sinking field devices.  Sinking I/O modules receive (or sink) current from sourcing field devices Sourcing-A term used to describe current flow between an I/O device and SLC 1/0 circuit- typically, a sourcing device or circuit provides a path to the source, high, or positive side of power supply Surge Current Per Point- The maximum amplitude arid duration (pulse) of current allowed for a given period of time and temperature Surge  Suppressor-A  device  used  to  absorb  voltage  transients  created  by  energizing  an inductive load to reduce electrical noise or to protect the output circuit For example, an R-C network, MOV (metal oxide varistor) or diode Token- The logical right to initiate communications  In a multi-master network a single token is passed between Initiators to make sure two nodes do not transmit at the same time UVPROM-An Ultra-Violet light erasable Programmable Read Only Memory module used to back-up, store, or transfer SLC 500 programs.  The SLC 5/01 and 5/02 can only read from a UVPROM. An external PROM programmer is used to program (write to) the device Voltage Category- The nominal voltage used to describe the module Watts  Per  Point-  The  maximum  heat  dissipation  that  can  occur  In  each  field  wiring  point when energized (page 3-466) Glossary
