When used in conjunction with the 8210A SmartStep controller, the Switch Driver allows for computer control of a variety of devices. The Switch Driver (Figure 1) provides 16 independent optically isolated outputs and inputs. Up to 16 cards may be attached to the 8210A SmartStep controller, for control of up to a total of 256 individual switch sections. Figure 1. Switch & Connector Location The outputs are configurable for steady state or pulsed operation, with programmable pulse widths that can be adjusted in order to optimize switching speed. The output drivers are optically isolated power MOSFETs that can deliver 350mA, 32VDC in steady-state operation or up to 1A when operating in pulsed mode. The outputs are protected with transient suppressors to help reduce the switching transients generated when driving inductive loads. Connections are provided on the card for the external power supply required by the switches to help simplify switch wiring. The Switch Driver card can be configured for 16-channel or 8-channel mode. In 16-channel mode, each driver is independently controlled. In 8-channel mode two bits are used per channel, with one bit being the inverse of the other bit. This mode can be used to drive two coil switches, one for set and one for reset. In order to accommodate a variety of switch types, the card is available in two different output configurations: Common Voltage (-001 assy) or Common Ground (-002 assy). In the Common Ground configuration, the output drivers provide voltage when turn on, sourcing current to the external device. In the Common Voltage configuration, the output drivers provide a path to ground when they are on, sinking current from the external connection. In either configuration, when the output is deactivated the driver is off, not allowing current to flow. MCE / Weinschel 3 SWITCH DRIVER (193-8055-000) IM-344 The Switch Driver optically isolated inputs can be used to verify switching operation when used with switches that can sense switch position. The card allows for a programmable delay period for the switch sense lines to settle, allowing the sensing delay to be adjusted to conform to the switch characteristics. The delay time is independent of pulse/steady-state output operation, and may also be used to provide a “recovery” or idle time between output changes, as required by some types of switches. Pulse widths and sensing delay can be set from 1 to 255 ms per switching operation in 1 ms increments. The pulse width default setting is 25ms. The sensing delay default is 10ms. The Switch Driver provides two additional auxiliary switches that are independent of the main outputs. These two switches provide there own separate inputs, and can be used to switch higher current loads, such as DC power supplies. The Aux1 switch is configured for AC/DC operation, and will handle 1A (+/-60VDC or AC peak), while the Aux2 switch is configured for DC operation, and will handle up to 2A at 60VDC. The two Auxiliary switches are not transient protected. The card contains a separate status output connector that can be used to drive LED indicators to provide a visual indication of the switch settings. The LED output port contains current-limiting resistors that provide approx. 5mA of current per LED. MCE / Weinschel 4 SWITCH DRIVER (193-8055-000) IM-344 Setting Card ID and Configuration The Switch Driver card ID and default configuration is set via an eight position DIP switch (S1) located in the upper corner of the card. The individual sections have a value of 0 when they are in the OFF position, and a value of 1 when they are in the ON position as indicated by the arrow located at the top of the switch. ON 1 2 3 4 5 6 7 8 VERIFY (SENSE) OFF/ON 16/8 MODE PULSE OFF/ON RESERVED ID3 (MSB) ID2 ID1 ID0 (LSB) Figure 2 – DIP Switch layout (shown with all switches in the OFF position) Each Switch Driver must have a unique card ID, which is determined by the settings of the DIP switch sections S1-5 through S1-8, labeled ID3-ID0. These four switches provide for a total of 16 ID’s, from 0 (00002) to 15 (11112). The ID value is set in an 8-4-2-1 binary fashion, with ID3 (msb) having the value of 8, and ID0 (lsb) having a value of 1.

When the Verify Mode is OFF (switch S1-1 OFF), queries as to the current switch position are simply reported as the last programmed state. When sensing is enabled (switch S1-1 ON), queries will read back the position in which they are currently sensed. Verify mode requires switches that have a means of indicating the current position, typically with a separate set of mechanical or electrical contacts. 16/8 channel operation is selected via switch S1-2. In 16 channel mode (switch S1-2 OFF), each of the 16 I/O circuits operate independently. In 8 channel mode (switch S1-2 ON), two bits are paired together and one bit is the inverse of the other. The channel pairs formed are OUT1 SET/OUT1 RESET, OUT2 SET/OUT2 RESET, etc. This mode can be used to drive two coil switches, one for SET and one for RESET. Pulse/steady-state output selection is controlled via switch S1-3. In steady-state operation (switch S1-3 OFF), the outputs are driven continuously when they are turned on. In pulse mode operation (switch S1-3 ON), the output drivers are turned on for the programmed pulse width time, after which they are disabled. Pulse mode operation is typically used with latching-style switches. Switch S1-4 is reserved for special operating modes, and should always be in the OFF position for normal operation.
