The M225 provides 16 independent latching SPST switches configured as quad 4x1 multiplexers. The switches have maskable interrupts that occur when the requested relay movements have been made.
The M228 is a 1MSPS 14-bit A/D converter module that samples and selectively stores differential analog signals along with a 32-bit time stamp at a rate up to 1MSPS.
The M223 (formerly Agilent E2290A) provides 16 data/actuator lines. These data lines offer TTL compatible inputs and open drain outputs up to 30 volts.
The M221 (formerly Agilent E2273A) provides 8 independent non-latching SPDT switches with maskable interrupts that occcur when the requested relay movements have been made.
The M218 (formerly Agilent E2270A) provides 16 independent latching SPST switches with maskable interrupts that occur when the requested relay movements have been made.
