The Model 4864 is an IEEE 488.2/GPIB/HP-IB to Relay Interface that provides 16 form ‘A’ contacts or 16 relay drivers for switching signals or for driving external relays. The 4864’s versatile commands let the user control the relays individually, step them as a single or multi-pole scanner, or step in a programmed sequence. The 4864 also includes eight isolated digital inputs that can be used to read external signals or contact closures. In control applications, these signals can be used to verify the response of the external system to the control outputs. The 4864 can also monitor the digital inputs and generate an SRQ and when the signals change state.
The Model 4864 is a member of ICS’s Mini-Box family of IEEE 488.2 interfaces which provide many new features while using less than one third the space of earlier designs. All Mini-Box interfaces are IEEE 488.2 compatible and use SCPI and short-form commands for ease of programming. All Mini-Box interfaces are packaged in a CE compliant metal case that is less than 1.6 inches (39 mm) high and 7.3 inches (186 mm) wide and can be rack mounted in a 1U high space.
IEEE 488 Bus Interface | The 4864's 488 Bus interface meets IEEE STD 488.1-1987 and has the following capabilities: SH1, AH1, T6, L4, SR1, PP0, DC1, RL0, DT1, C0 and E2 drivers. |
Primary Adresses | 0-30 |
SRQ Generation | SRQs are generated if the unit is not a talker, if SRQs are enabled and if an Enabled Event Status Register bit or an monitored digital input change occurs. Digital inputs are monitored by the Questionable register. |
488.2 Common Commands | *CLS, *ESE, *ESE?, *ESR?, *IDN?, *OPC, *OPC?, *PSC, *RCL, *RST, *SAV, *SRE, *SRE?, *STB, TST? and *WAI |
SCPI Commands | Used to set and query all programmable functions. The 4864 conforms to the SCPI 1994.0 Specification. |
Eight isolated inputs that can be queried and/or monitored for selected bit changes. Detected changes are saved and can be used to generate a Service Request (SRQ). | |||
Data lines | 8 | ||
Input signals | TTL/CMOS or contact closure to ground | ||
Input Levels |
|
