- Terminals 1 and 2 are data terminals for use by both remote sense and TEDS sensors. Before connecting the sensor, set which type will be connected in advance using the Remote Sense/TEDS setting on the Calibration menu page. If “Remote Sense disabled/TEDS enabled” is selected, calibration will occur automatically if a TEDS enabled sensor is connected.
- Select “Remote Sense enabled/TEDS disabled”, if a sensor with Remote Sense is connected.
- If using a sensor with 4 wires only (No TEDS or Remote Sense), Terminals 1 and 2 can be left open.
*Note: Never combine Sense and TEDS wires in Terminals 1 and 2.
D/A Output Connectors
These can output either voltage or current. They cannot output both at the same time. Set voltage or current in System Settings D/A Converter D/A Output Mode. Refer to the 9870 High-Speed High Performance TEDS Ready Indicator Installation & User Manual, Page 73.
9870 D/A OUTPUT CONNECTORS |
TERMINAL NUMBER | SIGNAL NAME | EXPLANATION |
9 | V-OUT | D/A Voltage Output |
10 | I-OUT | D/A Current Output |
11 | COM | D/A Output Common Terminal |
- The D/A output is isolated from this unit’s circuits.
Control Signal Input Terminal
9870 CONTROL SIGNAL INPUT TERMINAL |
TERMINAL NUMBER | SIGNAL NAME | EXPLANATION |
12 | CLEAR | This turns on when a hold is cleared in any hold mode except sample hold. Set whether or not CLEAR Signals are active or inactive in Hold Function Setting → CLEAR Signal. |
13 | JUDGE | Judgment output using judgment output control signals only functions when this is ON. Set whether or not JUDGE signals are active or inactive in Comparison Setting → JUDGE Signal. |
14 | HOLD | Holds function using hold start signals when this is ON. Disable this by selecting OFF in Hold Function Setting → Hold Mode. |
15 | D/Z | Sets the indicator value digitally to 0. This is active when both System Settings → Lock → Cal. Value Lock and Condition Setting → Digital Zero → Enable Digital Zero are set to ON. |
16 | SEL1 | If System Settings Setting → Memory is set to “by signal”, the SEL1 and SEL2 terminals can be used to select the active Setting Memory. Refer to the 9870 High-Speed High Performance TEDS Ready Indicator Installation & User Manual “9-1. Setting Memory” on page 71. |
17 | SEL2 |
18 | COM | This is the control input signal common terminal. |
- The control input signal is isolated from the unit’s circuits by a photocoupler.
- Signals are input to each terminal by shorting and opening with 18 COM. A current of about 20mA results from shorting. When using a transistor, select one with a resistance of at least 10 V and elements that allow the flow of at least 40 mA when on.
- You can confirm the status of the input signal on the screen shown in “6-6. Control Input Check” on page 48 of the 9870 High-Speed High Performance TEDS Ready Indicator Installation & User Manual.
Comparison Output Connectors
9870 COMPARISON OUTPUT CONNECTORS |
TERMINAL NUMBER | SIGNAL NAME | EXPLANATION |
19 | LL | Low low limit judgment output |
20 | LO | Low limit judgment output |
21 | HH | High high limit judgment output |
22 | HI | High limit judgment output |
23 | OK | OK judgment output |
24 | COM | Comparison output common terminal |
- The comparison output is isolated from the unit’s circuits by a photocoupler. Open collector output (NPN, current sync) 20mA/30V maximum collector current
- For the operation of each signal, refer to the 9870 High-Speed High Performance TEDS Ready Indicator Installation & User Manual “7. Comparison Setting” on page 49.
